Let's start by defining what a rational number is. It is a number that is expressed as a fraction. It could also be in decimal form, but only in circumstances when the decimal places are exact and not continuous or repeating. Let's take for example √7. Its exact value is 2.645751311. The decimals places are random and continuous that's why it can't be expressed into fraction. But if the decimal for is, say, 0.25, that is rational because it can be expressed to 1/4.
Now, the reason where it could be a fraction by using a denominator of 1 is invalid. All whole numbers have a denominator of 1. It is implicitly defined because any number divided by 1 is equal to the number itself. This is not a basis for a characteristic of a rational number. Therefore, the student is incorrect.
Answer:
Angles are congruent if they have the same angle measure in degrees. Try this Adjust any angle below by dragging an orange dot at its ends. The other angle will change to remain congruent with it. Angles are congruent if they have the same angle measure in degrees.
1,503 + 847 + 4,219 = 6,569
Answer:
Root 181
Step-by-step explanation:
Using distance formula, we know that the answer will be the square root of 181. Unfortunately, this is not a perfect square, and it is prime, so that number will remain the same.
